Ernst Barthel

Ernst Barthel
Ernst Philipp Barthel (17 October 1890 in Schiltigheim - 16 February 1953 in Oberkirch (Baden)) was an Alsace philosopher, mathematician, and inventor.
In the 1920s and 1930s he taught as a Privatdozent of philosophy at the University of Cologne. From 1924 on Barthel edited the magazine Antäus. Blätter für neues Wirklichkeitsdenken (Journal for new Reality Thinking), which served as the organ of the Gesellschaft für Lebensphilosophie (Society for Life Philosophy) founded by him in Cologne.
Barthel maintained philosophical friendships with his compatriots Albert Schweitzer and Friedrich Lienhard.
Philosophy and Earth theory
The main principle of Barthel's philosophy on the background of Christian Platonism was the Polarity, which he understood to be the most fundamental, constitutive law in all of nature. Besides his philosophical work he also published several works on geometry, further developing a non-Euclidean (Riemannian geometry, spherical) theory of geometry, which he called polar geometry. From this geometry he derived a new cosmology with the theory of a Great Earth, which states that the Earth is a maximal sphere in a cyclical space and its surface therefore a total plane, the equator plane of the Cosmos. The (total) plane, as well as the straight line and space as a whole, is flat, without curvature yet closed, running back on itself. Barthel considered this his most important theory, even the most significant thought of the century, as he writes in his autobiography.
While some of his academic colleagues stated that Barthel's theory is geometrically possible and consistent, others did not and accused Barthel of resorting to "the blight of personal calumny", deriding him for allegedly "teaching that the Earth is a disk" or outright declaring him crazy. Ultimately, Barthel's academic career was ruined. The Russian astronomer Leonid Leonidovich Andrenko considered Barthel's main thought among the most genius ever advocated.
Dismissal by the Nazi Regime
In November 1940 Barthel was dismissed from the University of Cologne by the Nazi Minister Bernhard Rust because of religio-metaphysical suspicions. Barthel's book Der Mensch und die ewigen Hintergründe was cited as evidence. Barthel was also dismissed for alleged political Francophilia. Until then, Barthel was a member of the National Socialist Teachers League.
